Linux以及Windows部署Seata服务

1. 确保 linux 有 Nacos 正常启动，并知晓正确的端口 用户名 密码

2. https://github.com/seata/seata.git 克隆 seata 项目到本地
3. 在 Github 下载对应你项目 SpringCloudAlibaba 建议版本的 Seata，我的版本是 2.5.5，建议 Seata 版本 1.3.0
4. 下载好后进入 seata/conf 配置目录，修改 file.conf

## transaction log store, only used in seata-server
store {
  ## store mode: file、db、redis
  mode = "db" #如果单机：file 如果是集群：db  并在下方配置你的Mysql数据源

  ## file store property
  file {
    ## store location dir
    dir = "sessionStore"
    # branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions
    maxBranchSessionSize = 16384
    # globe session size , if exceeded throws exceptions
    maxGlobalSessionSize = 512
    # file buffer size , if exceeded allocate new buffer
    fileWriteBufferCacheSize = 16384
    # when recover batch read size
    sessionReloadReadSize = 100
    # async, sync
    flushDiskMode = async
  }

  ## database store property
  db {
    ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.
    datasource = "druid"
    ## mysql/oracle/postgresql/h2/oceanbase etc.
    dbType = "mysql"
    driverClassName = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://sh-cynosdbmysql-grp-o5n8fbw2.sql.tencentcdb.com:20345/seata_server"
    user = "brath"
    password = "Lgq081538"
    minConn = 5
    maxConn = 30
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }

}

5. 修改 registry.conf

registry {
  type = "nacos"  //配置nacos

  nacos {
    application = "seata-server"
    serverAddr = "nacosip+端口" //nacosip+端口
    group = "SEATA_GROUP"
    namespace = "命名空间" //如果默认可以不填
    cluster = "default" //如果是集群请填写集群名
    username = "账号"
    password = "密码"
  }
  file {
    name = "file.conf"
  }
}

config {
  type = "nacos"

  nacos {
    serverAddr = "nacosip+端口" //nacosip+端口
    namespace = "命名空间" //如果默认可以不填
    group = "SEATA_GROUP"
    username = "账号"
    password = "密码"
  }
  
  file {
    name = "file.conf"
  }
}

6. 在克隆好的项目中找到 script/confing-center 找到 config.txt 文件

修改

store.mode=db

修改数据源

store.db.url=localhost:3306/seata_server?useUnicode=true&rewriteBatchedStatements=true
store.db.user=****
store.db.password=****

进入 script\config-center\nacos

如果是 windows 系统请确保安装了 GIT 以及 GIT bash

点击 nacos-config.sh 会自动把 config.txt 配置文件，配置到你的 Nacos 客户端中指定命名空间的配置中心供你的 Seata 使用

7. 进入 Seata/bin

sh seata-server.sh #启动seata服务
